The mechanisms responsible for the fast granulation of anaerobic sludge caused by Mg2+ and Ca2+ addition was examined in four lab-scale expanded granular sludge bed(EGSB) reactors. Results indicated that both Mg2+ and Ca2+ accelerated the sludge-granulation process and increased the amount of polysaccharides and proteins in the sludge. Energy dispersive x-ray spectrometry(EDX) analysis revealed that, in a mature granule, both Mg2+ and Ca2+ composed as phosphate and calcium was distributed primarily in the periphery of the granule, while magnesium distributed mainly in the interior. The addition of Mg2+ was more favorable for the nuclei formation, whereas the addition of Ca2+ was more favorable for subgranule growth and maintaining the granules' rigid structure. Results showed that the addition of Mg2+ in the nuclei formation stage and Ca2+ in the granule-growth stage accelerated granulation more than adding only one of them in the granulation process.

Sulfate reducing bacteria (SRB) is identified as the primary organisms responsible for the treatment of heavy metal wastewater. However, most heavy metals can inhibit the growth of SRB during heavy metal treatment processes. Sulfide is a metabolic product of SRB and it can precipitate or reduce heavy metals. This study focused on the effects of sulfide on SRB resistance to Cu(II), Hg(I) and Cr(VI) toxicity. First, we considered the existence style of various heavy metals with and without sulfide addition by sequential extraction experiments. Second, the particle size distribution was evaluated and the cell structure during the metabolism of a SRB culture, containing different heavy metals, was analyzed by particle size distribution and TEM analyses. Third, the evolution of sulfate under the influence of different concentrations of heavy metals with and without sulfide addition was investigated to evaluate SRB activity. The results indicated that sulfide played an important role in alleviating and even eliminating the toxicity of Cu(II), Hg(II) and Cr(VI). We also discuss the mechanism of sulfide on SRB resistance to Cu(II), Hg(I) and Cr(VI) toxicity.

Mesoporous silica KIT-6 with different pore sizes was controllably synthesized by hydrothermal meth- ods. The same contents of Pt were loaded on KIT-6 sup- ports to apply for propane total oxidation. Low-angle X-ray diffraction （XRD）, nitrogen adsorption-desorption, CO chemisorption and transmission electron microscopy （TEM） were carried out to investigate the physicochemical properties of the catalysts. The results reveal that different pore sizes of KIT-6 supports could affect the Pt particle sizes on KIT-6. The mesopores on KIT-6-80 and KIT-6- 130 effectively confine the size of the inside Pt nanopar- ticles during calcining. Pt/KIT-6-80 with the appropriate pore size as well as the Pt particle size exhibits the best catalytic performance with T50 （the temperature at which hydrocarbon （HC） conversion reaches 50%） of only 237 ℃. However, Pt particles prefer dispersing on the external surface of KIT-6-40 due to those too small pores.

Cell adhesion and migration play essential roles in tissue development and maintenance, and abnormal cell migration is involved in life-threatening diseases, including vascular disease, tumor formation, and metastasis. The advances in hydrogel-based 3D cell culture development facilitated the investigation of cell motility behavior, including cell-cell and cell-matrix adhesion and cell migration in a microenvironment more related to in vivo situations. Establishing advanced methods for these in vitro studies is thus necessary. Photo-sensitive proteins show advantages in remote and non-invasive regulation of hydrogels’ properties, and thus are of great potential in regulating 3D cultured cells’ behavior. In the presented study, we engineered photocleavable protein(PhoCl)-decorated hydrogels to regulate cell adhesion and migration of MDA-MB-231. The integrin-binding motif RGD was fused to the PhoCl and was decorated on the hydrogel. After being exposed to light at 405 nm, the PhoCl was cleaved and the RGD motif was released, resulting in detachment of the binding cells. The regulatory effect of the light illumination showed a time-dependent and cell density-dependent manner. Furthermore, the elimination of RGD by patterned light exposure completely suspended the cell migration to the corresponding region, suggesting a controllable regulation of the cell migration direction.

Peptide hydrogels have been widely used for diverse biomedical applications. However, our current understanding of the physical principles underlying the self-assembly process is still limited. In this review, we summarize our current understanding on the physical chemistry principles from the basic interactions that drive the self-assembly process to the energy landscapes that dictate the thermodynamics and kinetics of the process. We discuss the effect of different factors that affect the kinetics of the self-assembly of peptide fibrils and how this is related to the macroscopic gelation process. We provide our understanding on the molecular origin of the complex and rugged energy landscape for the self-assembly of peptide hydrogels. The hierarchical self-assembled structures and the diverse self-assembling mechanism make it difficult and challenging to rationally design the physical and chemical properties of peptide hydrogels at the molecular revel. We also give our personal perspective to the potential future directions in this field.
